===Adaptationist perspective and functional design===

Evolutionary psychology takes an [[adaptationist]] perspective to psychology. In evolutionary biology hypothesis about historical reasons for a particular trait can range from [[drift]], to [[phylogenetic constraint]]. Adaptationist are primarily interested in thos traits shaped directly by selection. In order to argue that a given trait is an adaptation evolutionary biologist and psychologist usually turn to ideas of [[functional design]].

In evolutionary biology hypothesis about historical reasons for a particular trait can range from [[drift]], to [[phylogenetic constraint]]. Adaptationist are primarily interested in those traits shaped directly by selection. In order to argue that a given trait is an adaptation evolutionary biologist and psychologist usually turn to ideas of [[functional design]].  

If a particular trait appears to be designed to solve a particular problem evolutionary proponents theorize that selection shaped it for that function. The only mechanism that proponents of evolution postulate that can create functional design is selection. Drift, constraint, neutral selection and byproducts do not create functional design.
